Fabric Highlight

Merino Ponti

Composition: 100% Merino Wool
Weight(s): 300 - 375 gsm
Micron gauge: 19.5μm
Part mid layer, part outer layer, our Ponti is 100% merino wool, double-knit for incredible insulation. The interlocking structure monopolizes on merino’s natural elasticity, allowing it to move with you while skinning up the north side of the mountain or reaching for that final arête. Merino Ponti is our fabric of choice for the Shak collection, named for the iconic Antarctic explorer Sir Ernest Shackleton. It’s ready for any and every expedition you find yourself on.

Reviews

The best

"It’s the best active outdoor sweater available. Most people I know wear Ibex and they are the coolest folks around. I got a large because my girth has increased as I’ve aged. The only sweater worth buying or wearing."

— David c. (5/5)

Shak 1/4 zip

"Ibex is a get what you pay for company. The shak 1/4 zip is the best cold weather base I have ever seen. Names like expedition, polar. thermal. . . are out there on the net, but nobody else does the cross knit which creates lots of air space to trap body heat. Thank you Ibex !"

— Canadian K. (5/5)

Perfect

"Perfect for casual, work, hiking, skiing. Wish your women's shake jacket used this fabric!"

— Jeanette Z. (5/5)

Ibex has the best Quality Made Merino Ever!

"I had purchased this same piece when I worked as a Founding Store employee at the Alpharetta REI 2015 using my employee benefits, used and wore it until last year when I donated it to my daughter’s BF attending U of Alabama. I wore a Large then, and now wear a Medium, so I decided to buy this again after a Fall/Winter without one as it was my favorite piece of apparel all these years…. So now I once again have this piece in sized Medium and get compliments on it everywhere I go"

— Craig M. (5/5)

A warm, perfectly long, layer

"It's a big pet peeve of mine when upper clothing won't fully fit under (or fully layer over) a bottom layer. I don't want any air gap. This product is perfect in that regard. I was looking for something a bit thicker, but this is a decent compromise for my need."

— Robert M. (5/5)

Great shirt but runs big

"I love the material and followed the size chart which should have fit. I’m 5’9” 175lbs with 42” chest. Bought the large and figured it would shrink a little after washing like most merino products. It didn’t and is definitely too baggy. Will be gifting it to someone larger. Ordered a medium so hopefully it fits like a glove."

— Jason C. (5/5)

Great sweater

"Warm. Good quality. My son loves it. Can be worn casually or for casual business or dinner. Looks good."

— Diane M. (5/5)

Im Not 6' 2"

"The Shak 1/4 zip is great ! It really regulates temperature. The only issue I have is that it's made for tall people. I have broad shoulders so I need an XL but I'm 5'7" so Ibex tops are always longer than I want them to be."

— Gregory P. (4/5)

Gift Given

"This shirt was well received. "It looks good on me""

— Jomarie Z. (5/5)

Replacing older Ibex pullover. Bought

"Replacing older Ibex pullover. Bought a quarter button Ibex pullover years ago. Did a lousy job protecting it from moths. This is a very attractive replacement. I intend to do a better job protecting it from the &£%#% moths"

— Bill B. (5/5)
